Officials in Irving said that there have been no reports of damages or injuries.

The earthquake happened as emergency personnel along the Texas Gulf coast, about 400 miles away, braced for a different potential natural disaster — Hurricane Harvey.

The Irving area recorded at least six earthquakes during a two-month period in late 2014, at a time when small quakes became more common in parts of North Texas. State officials in October 2014 amended rules for disposal well operators amid concerns that high-pressure injections can trigger earthquakes.
